Stable signal
Better range than 2G modules in my area. Power consumption is reasonable for LTE Cat.1.
5 FAQ
Q: What is the logic voltage level for UART pins?
A: The UART interface operates at 3.3V TTL logic levels. It is 5V tolerant but we recommend using 3.3V for best reliability.
Q: Does this package include an antenna?
A: The module itself does not include an antenna. You will need to purchase an IPEX compatible LTE antenna separately.
Q: What power supply is recommended for this module?
A: We recommend a 3.7V Li-ion battery or a 5V supply with an LDO regulator to ensure stable voltage during transmission peaks.
Q: Is an Arduino library available for this board?
A: Yes, please check our GitHub repository for the latest Air780E Arduino library and example sketches.
Q: Is the SIM card slot locked to a specific carrier?
A: No, the SIM slot is unlocked and supports nano SIM cards from all major network carriers.
